“Several pigeons, equipped with pollution measurement and GPS devices, were released at the ZeroOne Festival in San Jose, Calif., on Aug. 8. The birds… will be feeding data to the site via SMS. The data provides the location, carbon-monoxide levels and identification for each bird.”

Full, insane details at the PigeonBlog. (And if the pigeons start actually blogging, I’m headed to a shack in Montana…)
PS–Hopefully the birds will not be immolated by large, fire-breathing machines set to prowl the city tonight. Curiouser & curiouser.
